I'm Leo, owner of LC Heating & Air. I provide honest, practical gas furnace repair for Larchmont homeowners. We focus on safety, accurate diagnosis, and clear communication—no sales pressure, just the facts about your system.
Larchmont Village and the surrounding neighborhoods, from the Rossmore Avenue corridor to the Third Street area, have a unique character defined by homes built between 1920 and 1940. Because these homes were often built before central heating was standard, the HVAC systems we see are frequently retrofits added over the decades. Dealing with these systems requires more than just swapping parts; it requires understanding how the equipment interacts with your home's original architecture, ductwork, and electrical capacity.
At LC Heating & Air, we don't believe in one-size-fits-all solutions. Whether you are in a classic Craftsman or a renovated duplex, my team and I take the time to inspect your system's airflow, venting, and safety components before we ever suggest a repair or replacement. We are based right here on Fairfax Avenue, and we treat every Larchmont home as if it were our own.

Safety, combustion analysis, and honest repair
Common HVAC Challenges in Larchmont
Larchmont's older housing stock presents specific challenges. Many homes still have original ductwork that may be undersized for modern high-efficiency blowers, which can lead to airflow issues and premature equipment wear. In some pre-1960 homes, we still encounter older insulation materials that require careful handling during any service or duct repair.
We also see frequent issues with electrical panels that haven't been upgraded to handle the load of modern HVAC equipment. Before we recommend any repair or system upgrade, we check these constraints. My goal is to ensure that whatever work we perform is safe, reliable, and doesn't cause unexpected issues down the road.
Preserving Your Home's Character
Larchmont homeowners value their property's history, and we respect that. When we perform repairs or discuss system replacements, we look for ways to maintain comfort without damaging the architectural integrity of your home. We aren't here to push the most expensive equipment; we are here to provide an honest analysis of what your specific home needs.
If your system is worth repairing, we will fix it. If the age and condition of the equipment mean that replacement is the more sensible long-term investment, we will explain exactly why. We provide clear, written estimates so you can make an informed decision at your own pace.
Our Diagnostic Process
Every service call at LC Heating & Air follows a strict safety-first protocol. We don't just look for the part that failed; we look for the reason it failed. We verify flue draft, test for carbon monoxide, and inspect the heat exchanger for integrity before we even touch the mechanical components.
Once we identify the fault—whether it's a failed ignitor, a dirty flame sensor, or a pressure switch issue—we explain it to you in plain English. You will receive a written, flat-rate price for the repair before we start any work. No surprises, no hidden fees, and no pressure.
Repair vs. Replacement
One of the most common questions I get is, 'Leo, should I fix this or just get a new one?' My answer is always based on the data. If the repair is straightforward and the equipment has several years of life left, I will recommend the repair. We stock parts for all major brands—Carrier, Lennox, Trane, Rheem, Goodman, Bryant, and York—to get you back up and running quickly.
However, if the heat exchanger is compromised or the cost of repeated repairs is approaching the price of a new, more efficient system, I will tell you. We don't use safety concerns as a sales tactic. We provide the facts, and you decide what makes the most sense for your budget and your home.
Understanding Costs
We believe in transparency. Our diagnostic fee is $125–$175, which includes a full CO safety check. Common repairs like ignitor replacements typically range from $150–$250, while flame sensor cleaning is usually $100–$175. More involved repairs like gas valves or control boards range from $350–$600.
We provide a written estimate for every job. We don't offer 'cheap' fixes that fail in a week; we offer professional, lasting repairs that keep your home safe and comfortable.
Scheduling Your Service
We know that when your heat goes out, you need help fast. We prioritize same-day service for our Larchmont neighbors. Because we are local, we understand the access challenges of these older homes—whether it's navigating tight attic spaces or working around existing structural elements.
When you call (323) 970-3113, you're talking to a local contractor, not a call center. We'll get you on the schedule and provide an honest assessment of when we can arrive.
Your Safety is Our Priority
A gas furnace is a powerful piece of equipment that requires proper combustion and venting. We take this seriously. Every single service call includes a combustion analysis and CO check. We never leave a system running that we believe is unsafe.
If you ever smell gas, leave the building immediately and call SoCalGas from outside. Once the gas company has made the area safe, give us a call to investigate the source of the leak or the furnace malfunction.
Making the Right Decision for Your Home
Choosing between a repair and a replacement is a big decision. At LC Heating & Air, I help you weigh the age of your equipment, the cost of the repair, and the potential energy savings of a new unit. I'll show you exactly what we found during our inspection and explain how it affects your system's efficiency and safety.
You won't get a sales pitch from me. You'll get a professional opinion based on years of experience working on Larchmont's specific housing stock. Once you have the facts, you can make the choice that is right for your family.
How the visit works
We verify flue draft, test for CO, and inspect the heat exchanger before diagnosing the mechanical fault.
We trace the fault: ignitor, flame sensor, pressure switch, gas valve, control board, and blower components.
We explain the fault in plain language and provide a flat repair price. You approve; we repair.
We complete the repair and run the system through multiple heat cycles to confirm proper operation before leaving.
Cost factors we review before quoting
- • Type of failed component (ignitor vs. control board)
- • Age and model of the furnace
- • Accessibility of the equipment in your home
- • Need for additional safety or airflow adjustments

What Larchmont customers say about gas furnace repair
Verified reviews from homeowners in Larchmont and nearby neighborhoods who used our gas furnace repair service.
“Full system replacement in our 1930s Hancock Park home — not easy given the older construction. LC handled all the challenges: narrow access, old ductwork, low attic. Finished on time and on budget.”
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
